Phase 1 was a province-wide search and inventory compilation of previously studied potential water storage sites and diversion schemes. A database was developed to facilitate user-friendly data entry and retrieval as well as expandable for future data entry.

Phase 2 was an assessment and ranking of the sites by subbasin. Searchable and filterable Excel worksheets were provided for end-users to rank sites by numerous criteria.

This assessment of Alberta Environment’s infrastructure summarized the resources for operations and maintenance, services that were contracted out, identified other contracting out possibilities, the experience of other agencies with similar types of infrastructure and views of the stakeholders relating to contracting-out operations and maintenance. The assessment also investigated the interaction of Alberta Environment and Alberta Transportation for the future operation and maintenance functions to ensure a sustainable infrastructure.

The project involved the construction of four stormwater ponds / wetlands for the purpose of total suspended solid (TSS) removal. The project included treating water from three existing stormwater outfalls, carrying peak flow from 2 to 12 m3/s. The project is located within Fish Creek Provincial Park and contains a significant historical component.

The Malloy Drain Basin drains through a complex series of natural and constructed canals and drains. The main drain runs through the Town of Coaldale. The drainage channel has limited capacity. The committee consisting of the Town of Coaldale, Lethbridge County and SMRID retained MPE to look at cost options for a range of storage and release options, varying from 0.5 L/s/ha with significant storage, up to 4.0 L/s/ha with very little storage. Existing ‘natural storage’ and ponding areas have been included in the analysis, as well as constructed pond facilities.

Project Description:Weed Lake is a 600 hectare historic wetland that was drained in 1971. The project includes restoration and rehabilitation of the Wetland. The lake would also be the receiving body for treated wastewater and stormwater from the Hamlet of Langdon and would include supplemental inflow from the Bow River. The project includes inlet systems, outlet structure, storm water pond and pumpstation, dams and high-line dykes, channelization and crossings.

The MDP and FRP developed by MPE provides guidance for future development and a framework for solving existing drainage concerns in the Bearspaw area.

The MDP developed design guidelines, recognizing the limited capacity within the catchment area. It also proposed to utilize and provide proper outlets and spills from existing natural ponds: re-interconnecting ponds that had been inadvertently blocked or redirected by development activity. The MDP also falls within the Nose Creek Watershed, so recognized recently adopted release rates and promoted BMP’s and LID’s within the framework.

The Master Drainage Plan (MDP) provides guidance for future development so existing infrastructure, wetland and riparian areas are protected. The study area covers 49km2 and has a total catchment area of 820km2.

Project Description:Work included estimating the 2003 level of actual surface and ground water uses in the Sturgeon River Basin. This was prepared to allow AENV to complete a Water Resource Management Model for planning purposes within the basin.

Development of a 17m high dam and reservoir on the Serviceberry Creek to provide municipal water to surrounding communities and irrigation water to the Western Irrigation District. Reservoir capacity: 67,000 dam3 (54,000 acre-ft.)

Western Irrigation District receives stormwater runoff directly into their conveyance channels. Stormwater runoff from developed lands carries significant nutrient loading, high volumes and high rates. Their conveyance channels are significantly stressed. The WID required development of stormwater guidelines that the development community would follow when allowing release of stormwater into the conveyance channels. A framework for stormwater policies aimed at new urban developments was developed.

Site in question was originally designated as flood fringe, but recent river training works required new modeling. The client required sufficient information to show that development of the site was feasible without negatively impacting local floodplain levels.
